Abstract
The utility model discloses a late-model head lamp which can effectively reduce light interference when motor vehicles meet with each other, comprising a reflective mirror (1), a lamp holder (2), a bulb (3), an outer wall (4), a light-passing board (5), a light penetrating hole (6) and a convex lens (7). The light-passing board (5) is a round sheet whose center is provided with the light penetrating hole (6), and the diameter of the light-passing board (5) is equal to the internal diameter of the outer wall (4). A left surface is coated by chromium, and the distance from the light-passing board (5) to the center of the convex lens (7) is just equal to the focal length of the convex lens (7). The light emitted by the bulb (3) ejects on the convex lens (7) through the light penetrating hole (6), refracted into a bunch of parallel light beam through the convex lens (7), and the parallel light beam is ejected outside, illuminating road surface. The utility model eliminates angle light influencing the safe driving of a driver and enhances the safety of driving when motor vehicles meet with each other.
Description
The utility model is a kind of novel headlamp tool of motor vehicles such as automobile and tractor that light disturbs can effectively reduce the motor vehicles meeting time.
The headlamp of current mobility vehicles is made up of bulb, reflective mirror and concavees lens, bulb is contained on the focus of concavees lens, because head lamp bulb is one to have the entity of definite shape and volume, its illuminator--filament, also has certain shape and length, so light source can not be on the focus this point by absolute the assurance, but forms the illuminator with definite shape and volume around focus.After turning on light, the filament on the focus be reflected mirroring, concavees lens converge or directly form one parallel beam of light through concavees lens penetrates, this is useful light.The outer filament of focus then becomes many oblique rays after reflection and concavees lens refraction, oblique ray light has strengthened the shadow surface of headlamp, when the vehicle meeting, oblique line light enters the other side driver's the visual field, sense is dazzle the eyes in generation, stings to such an extent that the driver can't keep one's eyes open, and traffic accident easily takes place.When the method that adopts is both sides' meeting at present,, certainly will increase operation like this, disperse driver's notice, also increase the traffic unsafe factor to turn on light or to throw light at interval with the method for far and near lamp.Therefore, consider, should manage to change oblique ray into direct projection light from the safe driving aspect.
The purpose of this utility model is exactly a kind of novel headlamp of motor vehicle that can effectively change oblique ray into direct projection light, only the direct projection collimated light beam be seen through of design.The purpose of this utility model is to finish by the light-passing board that a center has loophole is set.
As shown in Figure 1, novel headlamp is made up of reflective mirror (1), lamp socket (2), bulb (3), outer wall (4), light-passing board (5), convex lens (7) etc.Light-passing board (5) is a circular sheet, and the internal diameter of the diameter of plate and outer wall (4) equates that the heart is opened a circular loophole (6) among the plate, and the distance at light-passing board (5) and convex lens (7) center just equals the focal length of convex lens.The inboard of the inboard of reflective mirror (1), outer wall (4), and the whole chromium plating in left side of light-passing board (5).
Operation principle of the present utility model is as follows: the light part that bulb (3) sends is directly passed loophole (6), planoconvex lens (7) refraction, becoming parallel rays penetrates, some is passed loophole (6) after reflective mirror (1) reflection, becoming parallel rays through convex lens (7) penetrates, and a part is radiated on the light-passing board (5) after reflective mirror (1) reflection, or directly be radiated on the light-passing board (5) by bulb (3), pass loophole (6) behind the Multi reflection of light-passing board (5) and reflective mirror (1), planoconvex lens (7) penetrates. Like this, light all passes through the focus of convex lens (7), be that loophole (6) is radiated on the convex lens (7) again, pool a branch of parallel beam of light through convex lens lens (7) and penetrate, illuminate the road surface, what just guaranteed to penetrate from convex lens (7) all is parallel beam of light, having eliminated affects the oblique ray that driver safety travels, reduced troublesome poeration, thereby end accident rate falls in the security of driving a vehicle in the time of can strengthening meeting.
Fig. 1 is a structural representation of the present invention.
As shown in the figure:
1--reflective mirror 2--lamp socket
3--bulb 4--outer wall
5--light-passing board 6--loophole
The 7--convex lens
Claims (3)
1, a kind of novel headlamp that can reduce the interference of motor vehicles meeting beam, form by reflective mirror (1), lamp socket (2), bulb (3), outer wall (4), convex lens (7), of the present utility model being characterised in that set up light-passing board (5), light-passing board (5) is a cast thin plate, the distance at itself and convex lens (7) center equals the focal length of convex lens, and the internal diameter of diameter and outer wall (4) equates.
2, the novel headlamp of reduction meeting beam interference according to claim 1 is characterized in that the center of light-passing board (5) has a circular loophole (6), and bulb (3) institute isolychn penetrates through loophole (6).
3, the novel headlamp of reduction meeting beam interference according to claim 1 and 2 is characterized in that light-passing board (5) is coated with the stronger materials of reflecting properties such as chromium towards a side of bulb (3).
